KEYSER TEXTILE MACHINE WITH CLOSED HOUSING2 Sheets-Sheet 2 Filed March 30, 1961 United States Patent 3,146,572TEXTILE MACHENE WETH CLOfiED HOUSING Johann .lacoh Keyser, Grahenallee16, Aarau, Switzerland Filed Mar. 3! i961, Ser. No. 99,430 4- Claims.(ill. 57-4) The present invention relates to a textile machine,especially a spinning machine with at least one closed housing forprotectively mounting drive transmission elements therein.

Each spinning machine comprises a frame or housing having mountedtherein all parts required for the textile technological process to becarried out and in which are also mounted the drive transmissionelements necessary therefor. The said transmission elements are, as arule, mounted in closed housings in order to protect the same againstundue manipulation. To this end, many spinning machines have at one endthereof a larger housing for the main drive transmission elements and atthe opposite end have a smaller housing for receiving further drivetransmission elements. Between these foremost drive transmissionstations, there are, in conformity with the specific type of machineinvolved, provided further housings or covers for purposes of protectingfor instance sensitive transmission elements against soil or unduemanipulation. However, the machine parts which serve the processingproper of the textile material involved are exposed in order to assure agood observation and easy handling at the respective working stations.Occasionally, individual portions of the machine are provided withscreens or the like in order to protect such portions for instanceagainst unfavorable air currents as they may be produced by the movementof fast running driving elements. A protection of the entiretechnological processing range of a machine has, however, heretoforebeen unknown with spinning machines. Merely in connection with machineswhich are out of operation for a longer period of time, it is known tocover the machine elements employed for the textile technologicalprocess with paper or cloth in order to protect the same against soilingand other harmful influences as they may be caused for instance by thehumidity content of the air customary in spinning mills. The sameapplies also to the transport of such machines if their size will permittransporting the machine in already mounted position.

The requirements put forward by the spinning industry with regard to theincrease in the production and improvement of the quality, can withheretofore known devices be met only to a limited extent. This is due tothe fact that the climatizing of the machine shop in which therespective machine is mounted can be adjusted only to a general mediumvalue which will meet the processing conditions of the fiber material toa certain degree and will produce air conditions tolerable for theoperators of such machines. The air currents caused by rotating machineelements were likewise held within permissible limits. However, afurther increase in the production and improvement of the quality of theprocessed material is not possible without material change in theprocessing conditions. In other words, it would be necessary to assurethat the processing of the fiber material will be effected under themost favorable climatic conditions which are dependent on themaintainance of certain temperatures and of a certain humidity contentof the air while harmful air currents must be eliminated as far aspossible.

It is, therefore, an object of the present invention so to design aspinning machine that the entire textile technological processingoperation of the machine will be carried out while being protectedagainst unfavorable outer influences and that the room in which themachine 3,14%,572 Patented Sept. 1, 1964 is located will be protectedagainst unfavorable influences caused by the machine.

It is a further object of this invention to provide a spinning machineas set forth in the preceding paragraph, in which all sensitive machineparts are covered up toward the outside as far as possible.

These and other objects and advantages of the invention will appear moreclearly from the following specification in connection with theaccompanying drawings, in which:

FIG. 1 illustrates a diagrammatic cross section through a spinningmachine with a protective cover according to the present invention.

FIG. 2 is a view of a portion of a ring spinning machine similar to thatof FIG. 1 as seen from the servicing aisle.

FIG. 3 is a perspective view of a pre-spinning machine with a protectivecover according to the present invention.

FIG. 4- is a perspective View of a drawing frame with a protective coveraccording to the present invention.

The objects of the present invention as outlined above have beenrealized by movably mounting at least one cover extending transverse tothe working direction of the machine in such a way that in the outercontour of the total cross section of the machine there is formed aclosed housing which is adapted completely to cover or encase the entiretechnological working field of the machine while said cover is adaptedat least sectionally to .be opened.

One of the simplest embodiments of the present invention consists inthat at least one cover is located near the zenith point of the totalcross section and is movable from this point. Furthermore, there existsthe possibility of mounting at least one cover near one outer end of thebase of the total cross section of the machine and to make said covermovable from this point.

According to a preferred embodiment of the invention, at least twocovers are mounted respectively near the zenith point and near one outerend of the base of the total cross section of the machine and aremovable from said two points in such a way that they abut with theirends at a predetermined point along the outer contour of the total crosssection. The cover itself may be designed in various manners. Thus, thecover may be so designed that it can selectively be rolled up, but ifdesired the cover may also be displaceable in form of a plate or may betiltable in form of a plate. Furthermore, there exists the possibilityto arrange two covers in series in such a way that the outer cover isshock-resistant and non-transparent while the inner one is transparent.

Advantageously, the arrangement is so selected that guiding means forthe lateral outer edges of the cover are provided in the outercircumference of the total cross section of the machine. When longmachines are involved, a cover extending over the total length of themachine is not practical for reasons of operation. In such instances,the arrangement may be such that the cover is subdivided along thelength of the machine and that at each partition guiding means for thelateral outer edges of each cover are provided in the outercircumference of the total cross section of the machine.

A cover as set forth above in able fully to meet the requirementsoutlined above inasmuch as it will in each instance assure a protectionof the textile technological working range of the machine to the desiredextent. The textile technological working range comprises the fiberfeed, the elements for the processing proper of the fiber material, andthe depositing of the processed fiber material on the machine. Dependingon the type of the machine and the processing operation, the space forthe textile technological working range will vary. Within said space, itis possible by means of the cover according to the invention to createthe most favorable climatic conditions for the fiber material withregard to temperature and humidity contents without affecting the freespace surrounding the machine and the operators in said free space. Alsothe air currents which might be produced by an increase in the speed ofthe machine will have no iriluence on the surrounding free space. Thesame applies to the air currents in the machine shop as they may beproduced for instance by opening and closing of doors.

While with heretofore known machines it was possible to adjust theclimatizing of the machine shop merely to a medium value for allmachines, the present invention will make it possible to adjust optimumclimatic conditions individually for each machine and for the specificfiber material being processed. The climatization of the machine shopmay then be limited to the ordinary renewal of air. Also the influenceof air currents produced by the machines, which air currents cause themovement of lint and dust, will be obviated by the present invention sothat the produced product will be improved and the operator will havebetter working conditions.

Referring now to the drawings in detail, the ring spinning machine shownin FIG. 1 comprises a frame known per se which includes vertical columns1, transverse struts 2 mounted near the bottom end of said columns 1,and transverse struts 3 at the upper end of said columns 1. In additionthereto, the frame of the machine comprises cylinder rails 4 extendingin longitudinal direction of the machine. Guided on columns 1 arespindle rails 5 and ring rails 6, whereas stands 7 of the creel aremounted on the transverse struts 3, and drafting frames 8 are mounted onthe cylinder rails 4.

According to the present invention, covers extending transverse to theworking direction of the machine are movably mounted on said machine.These covers follow a line corresponding to the outer contour of thetotal cross section of the machine. These covers form along said outercontour a closed housing by means of which the total textiletechnological working range of the machine is adapted to be completelycovered. This cover is adapted to be opened at least by sections.According to FIG. 1, the left-hand machine side is provided with a cover9 for covering the upper portions of the machine, whereas for purposesof forming a housing, a cover 10 is provided at the lower part of themachine. The cover 9 extends approximately from the zenith point of thetotal cross section of the machine to approximately the height of thetransverse struts 3, whereas the cover 10 is journalled near one outerend of the base of the total cross section of the machine and is movableupwardly up to the transverse strut 3. The embodiment of FIG. 1illustrates the cover 9 as a roll cover the slats of which are joinedtogether by hinges, so that it is possible to fold the slats together ina zigzag manner and to house the same above the creel in a positionfolded together. On the other hand the cover It) is illustrated as acover adapted to be rolled up leaving its winding roller 11 journalledon the trans verse strut 2. By pulling the cover 9 downwardly andpulling the cover 10 upwardlly, a housing will be formed which iscompletely closed along the contour of the total cross section of themachine. The said housing forms a complete cover for the textiletechnological Working range.

Preferably, the covers are transparent so that from the outside it canbe seen if a disturbance should develop at any point of the machine andwould have to be remedied. The covers may, however, also be madetransparent at those portions only where observations have to be made.For purposes of remedying a disturbance, only that portion is uncoveredby moving the cover away where the said disturbance has occurred. Forinstance for purposes of exchanging an empty pre-yarn bobbin andreplacing the same by a new bobbin, it will sufiice to raise the cover 9so that the creel will be accessible to the operator. If, for instance,a thread break has to be remedied, it is necessary at the respectivespinning station to move cover 9 upwardly and cover 10 downwardly sothat the fiber strand coming from the drafting frame 8 may be connectedto the thread end on the yarn body. After the respective disturbance hasbeen eliminated, the covers are again moved into their closed positionsso that unfavorable influences from the outside of the machine will notbe able to affect the technological processing operation.

On the right-hand side of the machine of FIG. 1, there are likewiseprovided two covers 12 and 13 both of which are adapted to be rolled up.The cover 12 winds itself upon a double winding roller 14 near thezenith point of the total cross section of the machine, whereas thecover 13 is adapted to be rolled off from a roller 15 which isjournalled at the outer ends of two successive transverse struts 2. Atthe base of the machine a stationary covering 11' or 15 respectively isprovided in longitudinal direction at least at the front side of thecover 19 or 13 respectively. The covering 11' rests with its lower edgeupon the floor and extends with its upper edge close to the cover, sothat the closed housing extends down to the fioor. The above alsoapplies with regard to the housing formations and the temporaryuncovering of the spinning stations for eliminating disturbances.

Instead of two covers 12 and 13, it is also possible to provide onecover only for the entire working range of a machine side so that forinstance the cover 13 would extend from the bottom of the machine to thezenith point of the total cross section of the machine.

FIG. 2 also shows the covers 9 and 10 which are arranged on theleft-hand side of the machine of FIG. 1. The illustration clearly showsthat these covers are closed in the left-hand portion of the drawing,whereas in the right-hand portion thereof the covers 9 and 10 occupy anopen position. FIG. 2 also illustrates a closed main drive frame 16mounted at one machine end for protectively mounting the drivetransmission elements which are driven by the electric motor 17 mountedon housing 16. From the main drive frame 16 there will extend thevarious smaller covered driving housings of which housing 18 covers thedrive for the drafting frame 8 whereas housing 19 covers the drive forthe spindle in the spindle bank 5. These housings 18 and 19 as well asthe parts therebetween are covered from the outside by a hingedprotective door 20. A further protective door 21 is likewise hingedlyarranged approximately at the level of the electric motor 17. These twodoors serve exclusively for protecting the operator against accidentsand do not form a part of the invention.

The textile technological working range starts merely adjacent the doors2t) and 21 and is adapted to be covered according to the presentinvention. FIG. 2 illustrates that the covers 9 and 10 do not extendover the entire length of the machine but are subdivided so as to formsections corresponding to the distance between two successive transversestruts 3. The outer ends of the extensions 22 connected to thetransverse struts 3 form a connecting point for guiding bars 23 whichextend along the outer contour of the total cross section of the machinefrom the bottom portion thereof to a level above the creel and formguiding means for the lateral outer edges of the covers 9 and 10. Theguiding bars 23 may in a suitable manner be connected to the lowertransverse struts 2 and to the stands 7 of the creel in order to assurea stable guiding for the covers. Above the creel of the machine theremay be arranged a stationary plate-like cover 24 which serves as tablefor the supply bobbins. To both sides of said plate-like cover 24 theremay be linked covers 25 adapted to be tilted upwardly so as to furnish afurther possiblity also from the top to reach the creel or the ends ofthe covers with their recesses.

FIG. 3 illustrates a pre-spinning machine which is likewise providedwith a cover according to the invention. As will be seen from FIG. 3,due to the shorter overall length of the machine, between the main driveframe 31 and the end drive frame 32 there is provided a one piece cover33 which extends in longitudinal direction of the machine and is locatedabove the upper portion of the machine. A similar cover 34 is adapted tocover the lower portion of the textile technological working range. Bothcovers 33 and 34 are adapted to abut along a predeterminedcircumferential line of the total cross section of the machine. The saidline is so selected that by opening one cover, a certain portion of thetextile technological working range of the machine is exposed, whereasfor instance the lower cover 34 has to be opened merely for exchangingthe full bobbins. The covers 33 and 34 have also in this instance theirside edges guided in guiding means which are mounted on the inner sidesof the main drive frame 31 or end drive frame 32. Depending on theavailable space, the covers 33 and 34 may have to be displaced merely orcan be rolled up. For instance a cover 34 adapted to be displaced isillustrated in FIG. 3, the side edges of which are formed Z-shaped in amanner that the extreme shank engages the guiding means which aremounted on the inner sides of the main drive frame 31 or the end driveframe 32 respectively. The guiding means may be formed as a groove. Thecover 34 enters a trough 34' which forms the bottom closing of themachine. The trough 34' extends either to the back of the machine orcloses towards to the floor. Similar to the covers 33 and 34 arranged onthe front side of the machine, further covers may be provided at theback side of the machine (not shown in the drawing) in order to form acomplete closure or housing for totally enclosing the textiletechnological working range, the said last mentioned housing may besectionally opened up in conformity with the requirements, for instancefor remedying a break in the thread.

FIG. 4 illustrates by way of example a so-called can drawing frame whichis likewise equipped with a cover according to the invention. In thisinstance, the sectional subdivision is eflfected according to theranges: fiber feed, processing portion proper, and depositing of theprocessed fiber material. When looking in working direction, astationary closure wall 35 is provided behind the can feed which wallcorresponds to the outer circumference of the total cross section of themachine as it is formed by the two lateral driving frames 36 and 37 ofthe machine. At the zenith point of the closure wall 35 there isprovided and connected thereto an abutment bar 38 which extends up to atransverse connection between the lateral driving frames 36 and 37 andforms a fixed connection between these parts. At the outer circumferenceof the closure wall 35, there is provided an upwardly displaceable cover39 which extends from the bottom of the machine to the zenith point ofthe closure wall 35 and between the latter and the lateral driving frame36. The cover 39 forms with a similar cover 40 on the other side of thecan feed a closed cover for the can feed. The drawing shows the backside of cover 40 only partially. The drafting frame portion proper ofthe machine which extends between the lateral driving frames 36 and 37is closed by a further cover 41 which is adapted to be displaced in adirection counter to the working direction of the fiber strands into anopen position. The lateral edges of covers 39, 40 and 41 are similar tothe other above mentioned embodiments inserted in guiding means, forinstance into the guiding means 42 for cover 39. Also the winding deviceconveying the drafted fiber strands and the can receiving said fiberstrand are enclosed in a housing-like manner.

Above the winding device there is provided an upwardly tiltableplate-like cover 43 which is tiltable about hinges 44 on the drivingframes 36 and 37 and the lower closure edge of which rests on a framewhich again is designed as guiding bar for two covers 45 and 46extending in vertical direction and surrounding the receiving can 47.The

covers 45 and 46 have their upper edges guided in frame guiding bars 43and at the bottom of the machine in a similar frame guiding bar 49. Theguiding means are also in this case formed by simple grooves provided inthe frame guiding bars 48 or 49 respectively similar to the guidingmeans 42 for the cover 39. In this way, it is possible to expose thetextile technoligical working range wherever a manual operation has tobe effected in the machine whereupon after completion of said operationthe respective cover may be closed again. This is possible with regardto the can feed, the drafting frame proper, the winding device below thecover 43, and also the receiving can 47. Nevertheless, the operation ofthe machine can easily be observed because the transparency of thecovers allows a proper observation.

The covers according to the invention are normally operable by theoperator of the machine. However, if so desired, they may be actuated bymechanical or electric devices which may be drivingly connected withother parts of the machine, for instance with the controlling device fora certain supply length or control devices effective during a break ofthe fiber material. The illustrated embodiments show that a coveraccording to the invention may be adapted in any suitable manner tovarious types of spinning machines.
